🌬 G.A.S AC1 Fan Controller Guide & Product Information

🌱 Intelligent Environmental Control for Grow Rooms

The G.A.S AC1 Fan Controller is a professional intelligent climate controller designed specifically for AC extractor fans used in grow rooms, grow tents, and hydroponic ventilation systems.

Built to automate grow room extraction systems, the AC1 constantly monitors environmental conditions and automatically adjusts fan speed to maintain stable temperatures and airflow levels. This helps growers create healthier indoor growing environments while reducing unnecessary fan noise and energy consumption.

Unlike basic manual fan speed controllers, the G.A.S AC1 intelligently regulates extraction airflow depending on environmental conditions, helping stabilise grow room temperatures and maintain proper negative pressure for efficient carbon filter operation.

• ✔ Intelligent automatic climate management
• ✔ Maintains stable grow room temperatures
• ✔ Smooth and quiet fan speed adjustment
• ✔ Ideal for hydroponic grow rooms and grow tents

⚡ Designed for AC Extractor Fans

The G.A.S AC1 Fan Controller is specifically designed for use with traditional AC inline extractor fans commonly used in hydroponic ventilation systems.

Compatible fan systems include:

• ✔ Systemair RVK fans
• ✔ Mixed-flow inline extractor fans
• ✔ Acoustic extractor fans
• ✔ Standard AC grow room ventilation systems

The controller is designed for AC motor fan systems and should not be connected directly to EC fans.

🌀 Automatic Temperature-Based Fan Control

The G.A.S AC1 automatically adjusts extractor fan speed depending on grow room temperatures to maintain a more stable growing environment.

As temperatures rise, the controller increases airflow automatically to remove excess heat. When temperatures fall, the controller reduces fan speed to help maintain environmental stability and reduce unnecessary noise.

This intelligent airflow control helps:

• ✔ Stabilise grow room temperatures
• ✔ Reduce plant stress
• ✔ Improve environmental consistency
• ✔ Reduce manual fan adjustments

Consistent environmental management is essential for healthier plant growth and improved indoor cultivation performance.

🔇 Quiet Fan Speed Adjustment

The G.A.S AC1 is designed to provide smooth and quieter fan speed adjustment compared to basic manual controllers.

Instead of abrupt voltage changes, the controller gradually modulates fan speed to reduce:

• ✔ Motor humming
• ✔ Airflow turbulence
• ✔ Vibration noise
• ✔ Excessive extraction noise

This makes the AC1 ideal for quieter grow room and grow tent environments.

💨 Maintain Stable Negative Pressure

Maintaining proper negative pressure is essential for effective carbon filter performance and odour management within grow rooms.

The G.A.S AC1 helps maintain stable negative pressure by regulating extraction airflow efficiently.

Proper negative pressure helps:

• ✔ Improve carbon filter odour control
• ✔ Prevent air leaks from grow tents
• ✔ Improve extraction efficiency
• ✔ Maintain stable airflow direction

This helps growers create cleaner, more controlled indoor environments.

🌬 Benefits for Indoor Growing

Environmental consistency is one of the most important aspects of successful indoor cultivation. The G.A.S AC1 helps automate ventilation systems for healthier and more stable growing conditions.

Benefits include:

• ✔ Stable grow room temperatures
• ✔ Improved humidity management
• ✔ Reduced extraction noise
• ✔ Improved carbon filter efficiency
• ✔ Better plant health and environmental stability

🔧 Installation Guide

The G.A.S AC1 Fan Controller is designed for straightforward installation into grow room extraction systems.

• ✔ Connect compatible AC extractor fan
• ✔ Position environmental sensor within the grow room
• ✔ Configure target temperature settings
• ✔ Allow automatic fan speed adjustment

For best results, pair with Systemair RVK Fans, carbon filters, acoustic ducting, and quick release clamps.
